Sealy and IDEO first collaborated in 2008, to rethink the design of its Stearns & Foster line. For years, Sealy, the largest mattress manufacturer in the world, had taken the standard industry approach to selling mattresses and watched market share and sales flatten; it knew something had to change. Stearns & Foster evolved from a single product design into a keystone for transforming the organization.

IDEO helped Sealy use actionable consumer insights to develop a scalable design methodology and new brand principles, which it applied to product design, operational and manufacturing decision-making processes, and sales and marketing strategy. This “brand-to-product” framework was subsequently used for three separate and consecutive product launches—Stearns & Foster, Embody, and Posturepedic—resulting in an overhaul of 85 percent of Sealy’s mattress portfolio.

Tempur-Pedic was already working with IDEO on a new mattress design when it acquired Sealy in 2013. It was also interested in how design thinking and human-centered design could improve its business. Once solely focused on the technological elements of designing a mattress, together with IDEO, Tempur-Pedic redesigned the outer shells of its mattresses to reflect the quality on the inside. This design change led to the company to look at new ways to infuse design into their products.

“The initial project was to design the mattress,” said Thomas Overthun, associate partner and design director at IDEO. “But the second project was to create a whole design language from the mattress out to what it meant for any other product, from pillows to blankets and other accessories. It eventually became bigger than just the mattress.”

Working on the Tempur-Pedic/Sealy relationship has been gratifying, said IDEO partner and design director Michael Hendrix, because although home goods can be thought of as simply products, nothing could be further from the truth. IDEO and Tempur-Pedic/Sealy changed the course of the mattress company's business through the transformative power of designing where, and ultimately how, people sleep. And in the process, the organization itself changed as well, moving siloed departments to cross-functional teams, with the brand division central to their cooperation, which led to consistent and aligned decisions across the board.

Some of the projects include:

Stearns & Foster Luxury Mattress
Sealy teamed up with IDEO to develop a design language for Stearns & Foster mattresses that would reestablish what the brand stood for. Through redefining brand principles and rounds of prototypes that focused on evocative details, the new Stearns and Foster mattress was the highest rated in Sealy’s portfolio since it started keeping records, and initial retailer orders were three times what management projected.

Next-Generation Posturepedic
An icon in the mattress industry was brought into the 21st century by developing a new product that delivered on the long-running promise of the brand. Together, IDEO and Sealy designed a product that focused on holistic back health. In its earnings report, the company said US bedding sales for the quarter were up 10.6 percent, to $253.4 million, a figure driven by the new product line’s introduction. According to Sealy’s Q3 earnings report, the Posturepedic launch represented the largest and fastest rollout in the company’s history.

Embody by Sealy
The project began by defining the market opportunities for all-foam beds, and ended with the modern, streamlined Embody mattress as well as a simplified design language, free of industry jargon, to help retailers talk about the mattress to customers. “Sealy collaborated with IDEO to create an approachable and attractive mattress that delivers the simple, healthy rest consumers want with a selling story they can easily understand,” said Jodi Allen, Sealy’s Chief Marketing Officer.

Tempur-Pedic Sleep System
Best known for the revolutionary, NASA-proven Tempur material inside its mattresses, Tempur wanted to transform the exterior of its mattresses to match the caliber of innovation inside. Together with IDEO, Tempur created a new sleep system, including an easily removable and washable fabric mattress cover. “Tempur-Pedic was born of innovation, but we were never a design-driven company until we worked with IDEO,” said Patrice Varni, senior vice president of brand marketing, Tempur Sealy North America, LLC. “Seeing consumer need in a new way through IDEO’s eyes has transformed us. Our product design, our creative psyche, our brand are all fundamentally changed by this sharper focus. This collaboration has given us all a renewed sense of pride.”

The challenge of how we’ll feed the exploding world population in the future—in a sustainable, cost-effective, and environmentally friendly way—is seeding an agricultural revolution in Europe.

In 2012, INFARM founders Erez, Guy Galonska, and Osnat Michaeli found that vertical farms could be a solution to urban self-sufficiency. These farms could allow people to grow vegetables and herbs in small spaces, with no soil and far less water.

An approach that’s captured the imagination of futurists for decades, vertical farming involves growing vegetables and herbs in stacked units or inclined surfaces, within which moisture, light, temperature, and nutrients are monitored, and controlled.

After creating their first vertical farming experiment in their apartment in Berlin, the founders brought together plant scientists and industrial designers to explore and develop vertical farming’s potential.

Since then, the startup has created custom growing systems for clients including Airbnb, Mercedes-Benz, and Weber. Most recently, INFARM installed a vertical farm growing herbs and vegetables at the Berlin branch of German supermarket chain Metro, the fourth-largest retail chain in the world, to sell to the public. It’s been profiled in Wired Germany, Süddeutsche Zeitung, The Guardian, and Zeit.

INFARM collaborated with IDEO to further explore their B2B offer, including concepts for the industrial design of the stackable, modular, climate-controlled units; the interaction design of an accompanying app to monitor and control the units, and its business model.

Urban farmers will sign up for “farming as a service,” comprising the units themselves, as well as a monthly subscription for seeds, cartridges filled with nutrients, and a pH regulator. Because they’re stackable, the modules can be scaled to suit anyone from a home grower to a restaurant chef or supermarket owner. And Erez claims a 1 square meter growing tray can yield four to six mature plants every day, 365 days a year, doubling that of state-of-the-art hydroponic greenhouses.

As well as remotely regulating each unit’s climate, the app will educate growers about new vegetables and herbs, selling packs of complementary seeds, with suggested recipes for them, and cooking instructions. Aiming to promote biodiversity, the firm will sell rare-breed and heirloom seeds too.

The startup has funding from the EU’s European Pioneers fund, and is now looking to secure investment to accelerate software development and ramp up their hardware production capabilities. Quite literally, it's growing its business.

Sesame Workshop is the nonprofit educational group that revolutionized children’s television with the launch of the landmark Sesame Street program in 1969. The show, which has since become a household name, is now watched in more than 150 countries worldwide. The Workshop also creates educational content for new media platforms, and partnered with IDEO to design a line of Sesame Street–themed apps for Apple’s iPhone. The Elmo Calls app, which functions as a utility app for parents and as an entertaining behavioral-development app for kids, is now one of the Top 100 paid iPhone apps in the iTunes store.

The collaboration began with a mutual desire to bring the show’s beloved characters to the iPhone platform—and to do so using a human-centered design approach. Child-development experts, educators, toy and interaction designers, and even the Sesame Street puppeteers weighed in on the design decisions. The team also worked closely with families throughout the project—from initial concepts to early prototyping to the final development—in order to stay focused on how children actually use the iPhone for play. The games were designed accordingly. For example, the team omitted menus from the Sesame Street apps to keep the experiences simple, playful, and fun for a young child. And each game features exclusive new Sesame Street videos, allowing players to enjoy “lean back” moments along with interactive ones.

The resulting iPhone applications let children engage with the favorite Sesame Street characters in a whole new way. Kids touch, shake, swipe, and tilt their way through original games featuring Elmo, Grover, Bert, Rosita, and the Count.

The titles, all of which are available from iTunes, include:

• Elmo Calls: Engages 2- to 5-year-olds in listening-skills practice and active participation during everyday situations.
• Elmo’s Monster Maker: Allows kids to create unique monster friends that dance and play with Elmo.
• Sesame Street Video Maker: Lets kids star in their own music videos, mashing recordings of themselves with popular Sesame music videos and adding their own stamps and special effects.
• Sesame Street Makes Music: Helps kids explore an array of instruments as they contribute to new renditions of classic preschool tunes with their Sesame friends.

How do you know when you’re successful in your work? You can check off a list of technical skills and expertise you bring to the table. You can use a career development rubric to make sure you’re hitting the right goals. But often, it’s your behaviors—the intangibles that are the most difficult to articulate—that make the most impact. Things like your ability to stay optimistic or your willingness to adapt when there’s no roadmap.

Because of the nature of our work at IDEO, these intangibles are a big part of what defines the experience of working at the company. So in 2012, a global team of designers from our U.S., Europe, and Asia offices came together to codify these values and behaviors as part of a larger effort to evolve IDEO’s career development platform. More often than not, when IDEOers hit road bumps in their career, it was not about what they were doing, but how they were doing it.

The team agreed that, in addition to identifying the technical requirements needed to progress through one’s career, it was just as crucial to give IDEOers the tools they need to navigate the complex culture. So they captured the values they believed were foundational to the culture and most strongly shared across the IDEO community, and put them to paper in The Little Book of IDEO. The title is meant to reflect its purpose for readers—a handbook that’s compact, useful, and free of any corporate jargon.

For IDEO-ers, this red cloth-bound guide provides a shared lexicon around both the hard and soft skills we need to succeed. It describes things like why IDEO is so loosely structured, where it comes from, and where it’s headed.

Most importantly, the book identifies the organization’s seven core values. These are by design specific, actionable, and integral to the kind of work we do and the environment in which we do it, going beyond common sense and general ethical practice. The intention: to foster meaningful conversations within the community about life at IDEO, and how to achieve success along the way. With each succinct expression comes a deeper explanation of why it matters, and how it shapes our experience at IDEO.

Over the years, the book has been roundly embraced by the IDEO community as an honest articulation of who we are, as opposed to what we aspire to be, and what we appreciate most about working together. When IDEOers first got their hands on it, a movement took shape to create videos that bring each of the core values to life. To depict the value of "Embracing Ambiguity," for example, New York-based designers built a makeshift cardboard rowboat, and while simulating a storm, navigated their way through uncharted territory with teamwork and optimism. San Francisco produced a Jacques Cousteau inspired look at the lifestyle and behaviors of designers in their natural collaborative habitat.

Through the process of making the videos, IDEOers came together to reflect on each of the values, talking through what resonated and what didn’t. It gave them a sense of ownership, and a platform through which to share their interpretations.

A Global Conversation

IDEO has a global presence—offices in two countries in Europe, two countries in Asia, and multiple locations across the U.S. As an organization that embraces a human-centered culture, it felt important to learn if the values resonated with the IDEO community in all of these locations, especially in a country like China, whose working culture is so different from the west. We saw the authenticity and resonance of the values as essential for attracting, motivating, and retaining local talent.

So how did The Little Book of IDEO land in Shanghai? Exploring this question would illuminate insights into how our own clients are often challenged to keep their company culture resonant within the global landscape.

A team of IDEOers in our Shanghai office took on the challenge of exploring the meaning behind each of the values. They were surprised with what they discovered—that despite the firm’s Western origins, locals felt largely connected to the values. It even helped to further solidify their identity as a community, even if it may have been in tension with local working culture, because it was rooted in a set of shared beliefs.

In some instances, the Shanghai team built on the existing values in order to refine the meaning for the local context. For example, the core value "Be Optimistic" rings true, but could sound naive when translated directly to Chinese, implying "rose-tinted glasses.” So in the Mandarin edition, an extra phrase was added to convey the measuredness we mean when we talk about optimism at IDEO. The lesson here: The treatment of something as fundamental and nuanced as our values requires authenticity and emotional connection, and therefore more of a transcreation process than straight translation.

Lasting Power

As an organization, we are designed to be flexible. This means we’re always changing—even when it comes to how we are structured—so that we can respond to the kinds of challenges that clients come to us for. In the midst of our constant evolution, The Little Book of IDEO is as resonant today as it was when it was published.

In short order, a community of designers, entrepreneurs, and social sector innovators embraced it, buying and downloading over 150,000 copies.

In April 2015, IDEO.org launched an exciting new evolution of the HCD Toolkit the Field Guide to Human-Centered Design. The Field Guide is the latest in IDEO.org’s suite of teaching tools and a step forward in sharing the practice and promise of human-centered design with the social sector.

A full-color, 192-page book, the Field Guide comes with 57 design methods, the key mindsets that underpin how and why IDEO.org believes design can change lives, a full slate of worksheets, and case studies from projects that show human-centered design in action.

The Field Guide was funded by more than 1300 backers in a Kickstarter campaign that reaching nearly three times its initial goal. IDEO.org received an amazing outpouring of support and strengthened its deeply held belief that human-centered design can push the social sector forward.

IDEO.org is a nonprofit design organization that launched out of IDEO in 2011 with a mission to improve the lives of poor and vulnerable communities through design.

In 2009, IDEO designed and launched the HCD Toolkit, a first-of-its-kind book that laid out how and why human-centered design can impact the social sector.

After a bit of brainstorming, we hit on the perfect idea: a Noam-enabled modern twist on Pong, the classic, endlessly absorbing old video game.

The Pong-a-tron is considerably more complex than its predecessor. It links together four iPads, two Raspberry Pis, 12 Arduinos, 24 stepper motors, a Mac Mini, two Node.js applications, a Processing sketch, an Objective-C app, and over 2000 RGB LEDs. Noam coordinates the entire menagerie by hosting a conversation between all the different elements.

The Pong game itself was written in Node and broadcasts paddle and ball positions, which are then rendered on various portions of the overall display. The paddles are translated into physical "pixel" strips along the edges of the Pong-a-tron, while the ball moves seamlessly from Arduino-controlled RGB LEDs to iPads and Raspberry Pis.

The Pong-a-tron was initially showcased at Solid Conference 2014 and is now a permanent feature in the lobby of IDEO Chicago. Stop by and see it in person at a studio event, or pay Noam a virtual visit.

The Pong-a-tron would not be possible without the incredible talent, skill, collaboration and brainpower of many IDEOers including: Joe Banks, John Grimley, Travis Lee, Zeke Markshausen, David Sjunnesson, Ben Syverson, Jon Wettersten, Garrett Winther, and more. Video by Ben Syverson.

Noam is a software-messaging platform created by IDEO to help hardware and software tools communicate with one another. To introduce Noam to the world, we wanted to build a physical manifestation of the platform, something that was—like Noam—fun and exciting but also remarkably simple to use.

Our bell’s impressive literacy is the result of an experiment in creating cheap, simple, and easy-to-use networks of wireless sensors.

Miha Feus, the interaction designer at the helm of the project, points out that Internet-connected things are set to reshape our lives in ways we can’t even imagine. But while the technology isn’t particularly complicated, setting up and connecting the necessary sensors and receivers is difficult and expensive with the solutions currently available, and the battery life in these systems is terrible. Because of this, Miha says, experimentation by would-be makers is being stymied.

Miha’s solution is a system called Beachsand that aims to make wireless sensor networks, in his words, “as numerous, cheap, disposable, and user-friendly as grains of sand on a beach.” Beachsand is made up of a postage-stamp-sized smart transmitter called a SenseGrain and an Arduino-based receiver he’s dubbed the SandCastle.

You can plug any analogue sensor, button, or switch into a SenseGrain, measuring light, temperature, motion… anything you like. The SenseGrain then gathers data from those sensors and sends it to the SandCastle, and from there, you can use the information as you choose.

Miha explains that Beachsand isn’t really a product in and of itself, but rather a tool to help people cheaply and easily prototype new products, services, and data experiments. He and fellow interaction designer Siri Johansson have already prototyped one use case: the studio’s kitchen bell.

I caught up with Miha and Siri to find out more.

‍

What exactly is a SenseGrain, and how does it work?

Miha: A SenseGrain is an ATtiny85 microcontroller, which is basically a very stripped-down version of an Arduino, plus a transmitter circuit and a coin cell battery.

You plug in any analogue sensor or switch and set how often you want it to send data. The device then goes to sleep and waits until it receives whatever type of input you’re measuring (in this case, until someone rings the bell). The SenseGrain sends data from the sensor to a receiver, which, at the moment, is an Arduino, where you can access, use, and manipulate the data.

What’s so good about it?

Miha: It doesn’t require any soldering or programming, so it's easy to set up and requires no maintenance at all. I programmed the microcontroller so that it’s very energy-efficient—on standby, it can last up to 30 years on a single coin cell battery (theoretically, at least). And it’s cheap! Each SenseGrain costs $2-3 to make.

Because they’re so inexpensive, you could put them anywhere—in a trash can, for example, to monitor when it’s being opened. Or if you don’t want to check your mailbox, you could put a SenseGrain in there and Beachsand could just let you know when you have post.

Currently, anyone with an RF receiver on the same frequency is able to receive data the sensor is sending, and I would like to keep it that way. Keeping sensor data open gives more people the opportunity to build something with that data.

Can you explain your experiment with the bell?

Miha: It's our Kitchen Bell 2.0. It brings an ordinary object into the age of the Internet of Things, where every physical object has a digital layer.

Beachsand makes our bell more than a static object, limited by its location and the reach of its sound, and gives it the ability to transcend space and time to be “heard” anywhere in the world.

How did you build it?

Miha: First we had to pick the right sensor to detect when the bell is being rung. The simplest one in this case was a tilt switch. We plugged the switch into the RF transmitter and taped everything on the clapper of the bell.

The second part was about receiving the message from the sensor and sending out an email. For that, we used an Arduino and an RF receiver connected to a laptop, which talks to a program called Processing. In Processing, we used some existing code for sending out emails, which we modified for our needs.

What did you learn building the Kitchen Bell?

Siri: It makes you think about what the right tone of voice and personality is for a specific object. We wrote a few drafts of the bell’s email to the studio. It should be light and funny, but also demanding—it’s a bell, after all.

What inspired you from outside IDEO?

Siri: There's an interesting ongoing discussion on the narratives told by smart objects. Hello Lamp Post is a really nice example of giving a voice and personality to inanimate objects, and a lot of effort was spent to define the right tone of voice.

This way of working with sensors and actuators has interesting potential applications in both directions: physical to digital or vice versa. A couple of examples that work in the digital-to-physical direction are the UID cookie box, which rewards tweets with cookies, and Tableau, which quietly prints stuff it “sees” in its Twitter feed.

‍

What are you planning next?

Miha: Our colleague Alistair Norris is working on another application for the front door, to measure traffic in and out of the studio. We plugged a roller switch into a SenseGrain, which triggers every time the door opens, and added an Ethernet shield to the Arduino.

Beachsand is really still a work in progress. The next step is getting PCBs (printed circuit boards) done, so that I won't have to build every sensor transmitter by hand, which can take anywhere from one to four hours. With a PCB it will take just two to three minutes. PCBs are also less prone to malfunction.

Hopefully I’ll make a version with everything on board, including a littleBits connector. Then I’d like to build actuators, or “ActGrains,” to work with the SenseGrains and the SandCastle.

We’ll let you know more about Beachsand as we prototype more applications for it in the studio—or you might just get an update directly from our trash can, our front door, or the kitchen bell itself! You can find the code here in the meantime.

‍

The bell that rings in the kitchen at IDEO London sounds rather more sophisticated than the analogue clang you might expect to hear when meals and snacks are ready. Our bell prefers to send articulate email messages, like this recent missive: “I summon you all to the kitchen table for a Beer-n-Nuts with [Arduino co-founder] Massimo Banzi. Come join us. Cheers, your Kitchen Bell.”

Scott Murray is an assistant professor of design at the University of San Francisco, code artist, D3 expert, and contributor to the Processing language.

Scott is endlessly excited about using code as a tool for visual explorations of all kinds, from fine art to interactive data visualizations, but his students aren’t always quite so jazzed about the idea of programming. “They’re used to Photoshop and Illustrator, chopping up pictures and vectors,” he says. “Coding moves them into a totally different working environment.”

It’s Murray’s job to pry open students’ minds to not only the languages of code but also to a new way of thinking—a developer’s approach to solving problems and building things. To this end, he’s helping to continue the development of Processing language, which is tailored specifically to the task of teaching designers and artists to code. “There are pedagogical tools embedded in the language itself,” he says, like the use of familiar terms such as “stroke” and “fill” as well as processes that help students think like developers when approaching the craft of design. “For me, design is all about systems—not creating an image, but a system that, when applied, results in an effective solution,” Murray says. “Processing, as a teaching tool, forces students to think beyond the output or image they want to create and describe the system they’re making and what it needs to do.”

Processing gives designers new tools and expands their design thinking. It’s free, open source, and available to all at processing.org.

Every Thursday in Palo Alto, IDEO’s Digital Shop hosts an informal lunchtime presentation by someone who is using code to create something surprising, useful, or generally awesome. Colleagues from all around IDEO gather for a meal and leave with a week's worth of ideas to chew on. We’ve asked some recent speakers to highlight a quick insight or tool they’d like to share.

I help organizations cut through complexity by shaping how they show up, through brand strategy, identity, and storytelling.

Working at the intersection of brand and business, I bring an editorial eye and a bias toward making—turning ideas into tangible experiences that people can understand, trust, and believe in.

My work spans government, healthcare, financial services, media, and consumer goods, from launching Gen Z-focused ventures to building innovation labs and reimagining legacy brands. I relish moments of ambiguity and enjoy translating across teams, perspectives, and priorities to move ideas forward.

I started my career in editorial and digital design, shaping cross-platform experiences and identity systems in publishing and agency environments. That foundation still shapes how I work today: I’m detail-oriented, collaborative, and overreliant on the Oxford comma. I hold a BFA in Visual Communication from the School of the Art Institute of Chicago.

For 25 years, I've asked the same question: Who does this design exclude—and what are we going to do about it?

My work spans human-centered strategy, inclusive design, and qualitative research, with clients ranging from Microsoft, Google, and Verizon to the National Science Foundation, and San Francisco Unified School District.

Before IDEO, I taught elementary school in East Palo Alto and spent a decade doing design work with social service organizations—where I learned firsthand what it costs people when systems are built without them in mind.

I am currently writing User Error, a nonfiction book about digital access and the design decisions behind it. I live in Oakland, California.

‍

My expertise spans brand, communication, and product design across tech, education, the arts, and social impact.

I believe great work demands both high-level vision and obsessive attention to detail, and only happens through collaboration.

I bring an inclusive, hands-on approach and a deep understanding of business, which enables me to consistently deliver excellence while always asking why.

Before joining IDEO, I worked at the brand firms Pentagram and VSA Partners. I began my career as a designer, leading teams at the School of the Art Institute of Chicago and the Milwaukee Art Museum. I hold an MFA in graphic design from Maryland Institute College of Art and a BFA in communication design from the Milwaukee Institute of Art & Design, and have taught at some of the best design schools in the US.

I am responsible for IDEO’s long-term success in China and working with clients to use design as a tool to enable growth. Specifically, I have helped Chinese companies design holistic brand solutions through the development of their products, communication, services, and innovation teams, and I have helped multinationals expand their presence and influence in China.

I advise global leaders on developing China-led innovation and capabilities.

In over 15 years in IDEO Shanghai, I have worked on projects that use design to elevate the quality of the experience of healthcare products and services, streamline processes that increase productivity, create spaces and programs that promote and enable inclusive communities, and build next generation mobility solutions that are planet-positive.

Before joining IDEO, I worked at Philips Electronics and the Electrolux Group in Italy, the Netherlands, and Singapore on a number of breakthrough commercial products. I am a member of the Young President Organization in Shanghai.

Most AI products today are built for work—a space with clear problems and established systems. One founder noticed a gap: personal life is messier, harder to systematize, and mostly left behind by the AI boom. So she built Cue, a personal AI that lives inside iMessage and group chats, to go where the other tools haven't.

‍

In this episode, Becca Carroll, IDEO's Chief Strategy Officer, talks with Sida Li, co-founder and CEO of Shared Context Lab, about staying anchored to a human need while the technology around her keeps changing shape, why she treats her business model with the same rigor she'd bring to a product, and what it feels like to build a company at this particular, disorienting moment in AI.

‍

The conversation also gets into how Sida makes design decisions: the language Cue uses to describe itself, the tradeoffs behind building inside iMessage instead of a new app, and a real story about a business idea that didn’t pan out.

‍

This is the second in a two-part series profiling founders from IDEO's Startups-in-Residence program. The first conversation is with Johannes Seemann, founder of Sooner, on designing GenAI for the emotional side of money.

Most personal financial tools are built to run the numbers and optimize towards a budget. While that works for some, most people experience money as a lived relationship that does not neatly fit into a spreadsheet. Johannes Seemann and Becca Carroll discuss why money is emotional before it is mathematical, and what a human-centered approach to building a generative AI financial product looks like in practice.

Mina Seetharaman talks with Scott Shigeoka, author of Seek and Head of Curiosity Cultivation at the Eames Institute, about what distinguishes genuinely curious leadership from performative curiosity, how power dynamics shape curiosity, and why practicing curiosity can restore energy rather than drain it.

Mina Seetharaman talks with David Epstein, author of Inside the Box and Range, about why total freedom often produces average work, how leaders can design useful limits on purpose, and what organizations such as General Magic and Pixar reveal about the relationship between boundaries and creativity.
